ALCOHOL-GAS BURNER.

To all whom it may concern:

Be it known that I, TVEsLEY E. OOOHRAN, citizen of the United States,residing at Montgomery, in the county of Montgomery and State ofAlabama, have invented certain new and useful Improvements in Alcohol-Gas Rumors, of which the following is a specification.

The present invention provides a burner especially designed for heatingsad irons and utilizing alcohol as fuel, the construction being such asto insure economy in consumption of the fuel and a thorough andeffective heating of the irons.

The invention supplies a sad iron heater of the nature aforesaid whichis light, easy of manipulation, adapted to be readily cleaned shouldoccasion require, efficient in use, compact in construction and reliablein operation.

For a full understanding of the invention and the merits thereof andalso to acquire a knowledge of the details of construction and the meansfor effecting the result, reference is to be had to the followingdescription and accompanying drawings, in which:

Figure 1 is a central longitudinal section of a burner embodying theinvention; Fig. 2 is a section on the line ww of Fig. 1; and Fig. 3 is asection on the line y-y of Fig. 1.

Corresponding and like parts are referred to in the followin descriptionand indicated in all the views of the drawings by the same referencecharacters.

The device comprises a burner, a generator, a collecting chamber and asuperheater.

The burner 1 consists of a tube having a series of perforations alongits length forming outlets. One end of the tube is closed by means of aplug 2 and the opposite end is provided with a mixing chamber 3. Theouter end of the opening formed in the mixing chamber is contracted andthe inner end is enlarged and said mixing chamber is threaded orotherwise secured to the burner tube 1. A heat conducting tube 4 isarranged above the burner 1 and adj acentthereto and is secured to theburner tube, either by being brazed thereto or in any convenient andsubstantial way. One end of the heat conducting tube is closed by meansof a plug 5 and its opposite end is connected to the generator 6 bymeans of a thimble 7 or other way.

Specification of Letters Patent. Application filed November 27, 1908.

iatented Feb. 8, 1910. Serial No. 464,564.

The generator 6 consists of a tube of approximately elbow form and isfilled with wire gauze 8 or other material generally employed forretarding the flow of liquid fuel and distributing same to insureeffective ac tion of heat thereon, whereby said liquid fuel is convertedinto vapor or gas. The outer end of the generator 6 is adapted to beconnected to a reservoir or tank, not shown, in any manner, so as tosupply the liquid fuel to the generator when the burner is in operation.The collecting chamber 9 projects vertically from the generator 6 andconnects with the latter at a point between its ends. A cap 10 closesthe upper end of the collecting chamber and is provided at a centralpoint with a threaded opening to receive the threaded portion of aneedle valve 11, the latter being provided at its outer end with abutton or finger piece in the well known manner. A tube 12 is locatedcentrally within the collecting chamber 9 and its upper end is adaptedto be closed by the needle valve 11. The lower portion of the tube 12extends across the generator 6 and beyond the lower side thereof andcurves toward the burner and is pro vided with a nozzle 13 whoseextremity enters the contracted end of the mixing chamber 3, so as todirect a jet of gas therethrough when the burner is in operation.

The burner l and heat conducting tube 4- are designed to occupy anapproximately horizontal position, whereas the collecting chamber 9extends vertically. The horizontal portion of the generator 6 is in linewith the heat conducting tube 4 and rests upon the edge portion of theburner l to which it is attached.

The alcohol or other liquid fuel is supplied to the generator 6 inregulated quantity in the manner well understood and is converted intovapor or gas from the heat derived from the burner. The vapor or gaspasses from the generator into the collecting chamber 9 and thence intothe tube 12 and outward therefrom through the nozzle 13 into the burner1 where it is consumed as it issues from the outlets in the sidethereof. It is to be understood that a space exists between the nozzle18 and the end of the mixing chamber 3 for the ingress of air, the jetof gas issuing from the nozzle 13 creating a vacuum in the mixingchamber resulting in drawing air into said chamber for admixture withthe gas, so as to insure a perfect combustion and to produce an in--tense heat. By having the heat-conducting tube 4 located directly abovethe burner I it is intensely heated and by the well known law ofconduction and convection transmits the heat to the generator 6, so asto convert the liquid fuel into the form of vapor or gas, which'isutilized for producing the heat, said gas being consumed as it issuesfrom the outlets in the side of the burner 1.

The burner is exceedingly simple and compact in ;construction, capableof being cheaplymanufactured and effective and re- -liab]ein operationand is also light in formation and adapted to be easily and effectivelymanipulated.

Having thus described the invention what isclaimed as new is:

l. A device of the character specified comprising a burner, a heatconducting tube adjacent to the burner and connected therewith, agenerator having an end portion adjacent to the burner and connectedwith the heat conducting tube, a collecting chamber extending laterallyfrom the generator and having its upper end closed, a tube housed withinthe collecting chamber and having its upper end provided with a valveseat and its lower end curved laterally and provided with a nozzlearranged to deliver a ct of gas into the burner, and a needle valveextending through the closed end of the collecting chamber and engagingsaid valve seat.

2. In combination a burner, a generator arranged within the heating zoneof the burner a heat conducting tube connected with the generator anddisposed above and in vertical alinement with said burner, a collectingchamber projected from the generator, a tube located within thecollecting chamber and having its upper end open and spaced from the topof the collecting chamber and its lower end extending through thegenerator and provided with a lateral nozzle arranged to deliver gasinto one end of the burner, and a valve extending within the open end ofthe tube for regulating the gas admitted to said tube.

3. In combination a burner, a generator having a portion arranged withinthe heating zone of the burner, a collecting chamber projected from thegenerator a cup forming a closure for the upper end of the collectingchamber, and having a threaded opening formed therein, a tube locatedwithin the collecting chamber and having its upper end open and itslower end extended through the generator, and provided with a nozzlearranged to deliver a jet of gas into the burner, and a needle valvethreaded in the cup and adapted to enter the open end of the tube forcontrolling the passage of gas to the burner.

4-. In combination a burner provided at one end with a mixing chamber aheat-conducting tube adjacent to the burner, a generator having an endportion adjacent to the burner and connected to said heat conductingtube and having its outer end curved, a collecting chamber extended fromthe generator at a point between its ends, a tube located within thecollecting chamber and extended through the generator and having itsprojecting end curved toward the burner and provided with a nozzledischarging into the said mixing chamber, and a valve to control thereceiving end of the tube and fitted to the extremity of said collectingchamber.

In testimony whereof I aflix my signature in presence of two witnesses.WVESLEY E. COCI-IRAN. [11. s.]
